i My invention relatesitothe of in warfare` and has particular-referenceto the laying of mines from submarine boats.i

My invention contemplates the'discharge` of mines from the waist of theship through one or more properly located expulsion tubes. My inventionis illustrated, more or less schematically in the accompanying drawings,f

in which, Y Y f g p.. Figure l is a longitudinal sectionalview ot themidship portion'ofthecraft, and,

Figure 2 is a transverse sectional .Viewl planeof :the line 2--2 of'Fig-1 vk taken on the The outer hull ofthe Vsubmarineboatfisillustrated at 3, and the inner hull thereof at 4. Forwardly in theadmidships compart-VM nient 5, racks 6, 6 arelocated for the stowing ofmines m, m, as shown and a plurality ofV expulsion tubes?, 7 are mountedywithin theN y au compartment inv proximity to the'racks, these tubesextending through the bottom andv being inclined aft as illustrated.

Each of thetubes 7 is'providedwith a lower' Vor outer cover 8 and anupper or innercover 9, both operable from within the compartment in amannerto be pointed out presently,
